Title: Connecting system for attendant board of automatic exchange device
Inventor: ISHIHARA YUKIO
IPC: H04M3/60
Filed: 1982-10-21
Abstract: PURPOSE:To decrease the number of cables between a telephone exchange device and an attendant board, by connecting various types of information for communication on a loop type line with digital multiplexing between an automatic exchange device and the attendant board. CONSTITUTION:An incoming call to an incoming trunk 2 is informed to a central device 10, and the device 10 transfers a code showing an incoming display to a main loop interface device 8. The device 8 inserts an incoming display code to a slot for control signal and transmits it to a transmission line. A follower loop interface device 7 detects the incoming display code and transfers it to a signal converter 6. The converter 6 decodes the incoming display code and performs the incoming display to an attendant board 4. When an operator of the board 4 gives an answer to the incoming call, the device 10 closes a channel between a trunk 2 and a position trunk 3. A voice signal is supplied to a talking circuit of the board 4 through the trunk 3. The voice of the board 4 is supplied to the channel of the trunk 3 for talking. In such a constitution, just two pairs of cables suffice for transmission and reception of data.

IPC: F04C28/00
Filed: 1985-08-24
Abstract: PURPOSE:To obtain the stable delivery switching control by connecting a deliv ery pipe passage and a pressure working chamber when the load for a cooler is high and disconnecting the said connection when the said load is low. CONSTITUTION:When the load for a cooler is high, a spool valve 33 is opened so that the after-intake-and-throttling pressure on the intake flange (7) side becomes equal to the before-intake-and-throttling pressure on the evaporator (E) side. After this, a seal valve 41 is opened by a spool valve 39, and the deliv ery pressure in a delivery pipe passage 32 is sent to a pressure working chamber 29. At the same time, a bypass passage 26 is closed to let the compressor run into 100% capacity operation. On the other hand, when the load for a cooler is low, the reversed operation is carried out. With this contrivance, a stable capacity switching control can be obtained without being affected by the varia tion of differential pressure between the intake pressure and the delivery pres sure, which is caused by the factors other than the load for the cooler.
